20.500.12556/RUL-68517 Izboljšanje učinkovitosti in informacijske vsebine gozdne inventure s stratificiranim vzorčenjem Improvement of the efficiency and of the information content of forest inventory by means of stratified sampling S stratificiranjem gozdne površine v homogene sestoje povečamo učinkovitost gozdnih inventur. V gozdu Hrastičje smo s stratificiranjem s pomočjo fotogrametrično izdelane sestojne karte izboljšali oceno poprečne lesne zaloge, hkrati pa smo povečali konkretnost podatkov terenskega snemanja. Primerjava stratificiranega in nestratificiranega vzorčenja v obravnavanem gozdu kaže, da pri neupoštevanju stratificiranja potrebujemo za dosego iste točnosti ocene lesne zaloge 50 % več vzorčnih ploskev. Fotogrametrična sestojna karta je dober pripomoček pri stratificiranju gozdne površine. By stratifying areas into homogeneous stands, the efficiency of forest inventory is increased. Through stratification carried out with the help of a chart of aerially mapped stands, we have improved the evaluation of the general growing stock in the forest of Hrastičje. At the same tirne we have also increased the concreteness of collected data. A comparison between stratified and non-stratified sampling in the mentioned forest shows, that when stratification is not taken into consideration, we need 50 % more sample plots in order to achieve the same accuracy when evaluating growing stock. An aerial stand map is an excellent instrument when stratifying forest areas. gozdna inventura stratificiranje sestojne karte forest inventory stratification stand map true false false Slovenski jezik Angleški jezik Znanstveno delo 2015-07-10 21:06:56 2015-07-10 21:06:56 2024-08-09 03:46:42 0000-00-00 00:00:00 1989 0 0 Str. 5-20 Št. 34 1989 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*52 0351-3114 14026242 Izboljanje_URN_NBN_SI_DOC-UV4CDYGE.pdf Izboljanje_URN_NBN_SI_DOC-UV4CDYGE.pdf 1 709141C5B9783769DB051F8CCFF58198 79ea0978b4f51589872f52a1b4a0f15f2624b36bebb3e91addc5106a703eed16 d9aa7a7f-557d-11ef-8f74-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=188351 Biotehniška fakulteta 0 0 0
